Diagnostic Trouble Codes (DTCS)

The control module will store a diagnostic trouble code (DTC) if it detects a fault. The driver's door module can store up to 10 diagnostic trouble codes (DTCs).

Should a fault disappear for any reason after being permanently stored in the control module as a diagnostic trouble code (DTC), the information remains stored in the control module.
